Abstract
A pixel circuit and a driving method thereof are provided. The pixel circuit includes first to second pixel electrodes, first to third liquid crystal capacitors, a first storage capacitor and first to third switches. The first liquid crystal capacitor and the first storage capacitor locate between the first pixel electrode and a first common voltage. The second liquid crystal capacitor locates between the first and the second pixel electrodes. The third liquid crystal capacitor locates between the second pixel electrode and the first common voltage. The first switch has ends for receiving a data voltage and a scan signal and coupled to the first pixel electrode. The second switch has ends for receiving a second common voltage and a reset signal and coupled to the first pixel electrode. The third switch has ends for receiving a reset voltage and the reset signal and coupled to the second pixel electrode.
